Model: 21 (Markfinder)Production Years: 1947-1952Description:50mm F3.5Curious
Camera, having Projected framelines rather than a rangefinder. This is
obtained by a high-quality assembly of mask, mirror and semi-silvered
mirror. This also provided for a higher-eyepoint, and freedom from
eye-position error. The model 21 also provided for automatic
shutter-cocking with film advance, as did the C-4 and C-44. A notable
achievement in the Argus line. The film ran from left to right, as
opposed to the C/C2/C3. Flash synch was provided for "M" and "F" Bulbs,
with a selector switch on top. The Lens of the model 21 was removable,
allowing for use on enlargers. It also exhibited a hot shoe, coated
lens, and shutter speeds from 1/10th to 1/200th, plus "B". Rewind was
facilitated by retracting the advance "fork", and rewinding as normal.
